Chapter VI is appropriately named Understanding By Faith as the entire chapter is devoted to revealing the future enlightenment of some of the Buddhas great disciples. Again, let me stress that each of these people, as great as they may be, do not attain enlightenment in this Saha world, nor do they do so by practicing as the Buddha instructs us, that is keep, read, recite, copy, and teach the Lotus Sutra. These disciples as great as they may be are not capable of practicing the Lotus Sutra in this world and only become Buddhas in realms very much unlike our own.
